Dantalian brews a potion that paralyzed people. It required water, a flower, a scorpion and an object that has touched the desired person's lips. Zile used it to paralyse Prue, and Dantalian used it to paralyse Zile.

Transformation: Used by Warlock Piper to transform Craig into a pig and by Warlock Phoebe to transform Leo into a stick in the mud. Piper later reversed her and Phoebe's transformations on Craig and Leo.

This is the first of two episodes where all three sisters are evil, the other episode being "12 Angry Zen". It is the only episode where Prue is evil, and the third for both Piper and Phoebe.

Leo dies for the second time.

The Book of Shadows' pages were somewhat blackened when it turned evil, a sign of the strength of the evil magic flowing through the Charmed Ones.

Future Phoebe and Paige both arrive to this time from 2003 (Cat House) to when evil Piper and Phoebe respectively "froze" and shattered Leo.

Phoebe's fears about her love for Cole pulling her toward evil proved deadly accurate, as just over a year later, she briefly became Queen of the Underworld after Cole was possessed by the Source.

After Dantalian was vanquished, Prue says "Well that was the wedding from hell", which was the name of an episode in season one.

The restaurant where Prue has lunch with Justin, is the same one featured in "Be Careful What You Witch For" on Prue's date with Dick, and again in "Pre-Witched" when the warlock kills the girl when the sisters refuse to kill him.

This episode scored 5.4 million viewers.

In the beginning of this episode, Phoebe is watching "Kill It Before It Dies", which was established as her favorite movie in the season 2 episode "Chick Flick". It was also mentioned by Cole in an earlier season 3 episode.
